There are definitely softer and firmer versions of Boost out there, but one thing they all seem to have in common is crazy good impact protection for the amount of material. Anyone who has tried a soft Boost running shoe knows how soft and comfortable it can be, but I also heard they came out with a new Boost training shoe, the Crazytrain Elite, which is made for stability because weight lifting requires a shoe with very little compression. The Boost on the Barricade tennis shoe is definitely on the firmer side, probably because they want it have the court feel of the non-Boost Barricade, but even though it's not the most comfortable shoe out there, I know I can depend on it to protect my knees.
Honestly, I don't think Adidas puts as much effort into their tennis shoes as they do for their running and basketball shoes. I guess it's all about the money. For me, an ideal Boost tennis shoe for the masses would have a midsole similar to the D Rose 7 (which is supposed to be the same firmness and thickness as the Crazylight Boost). To me, that has the ideal combination of court feel, stability, comfort, and impact protection for tennis. If they come up with a tennis specific shoe that has that kind of midsole, I'll grab it right away, but if they don't that fine, I'll get another one of the their basketball shoes. I'm really hoping the next iteration of the Crazylight Boost will fix their heel slippage problem. If not, I might get the Crazy Explosive Low even though it probably won't last long for tennis, but it's a great looking shoe.
